Problem in TabControl and frame/panel. priyamtheone2-Mar-09 20:29 priyamtheone 2-Mar-09 20:29  Hi everyone, I am facing two problems, kindly refer: 1) In Vb.Net 2005, how is it possible to make the TabPage.Text to appear when the DrawMode of a TabControl is set to OwnerDrawFixed. I have even tried to set the TabPage.Text in the Form_Load event but of no avail. Plz help. 2) How can I draw a frame or groupbox or panel whose style effect is 'Raised'. In most of the cases when we set the Frame or Panel borderstyle to 3D, the style effect is 'Sunken'. But I want it to be 'Raised'. This is possible if you add the reference- Microsoft Forms 2.0 Object Library, choose Microsoft Forms 2.0 Frame from 'Choose Toolbox Items' and set its SpecialEffect property to Raised. But that is a COM component and I want it to be done through core .Net framework components. How is it possible. clear datagrid in vb.net hrishiS2-Mar-09 19:45 hrishiS 2-Mar-09 19:45  Hi to all... Could anyone please tell me how to clear the datagrid (not datagridview) in vb.net2005 Thanks in advance Himangshu I am a learner Always Re: clear datagrid in vb.net Christian Graus2-Mar-09 19:48 Christian Graus 2-Mar-09 19:48  Clear the rows or the data source ?

Re: clear datagrid in vb.net hrishiS2-Mar-09 20:36 hrishiS 2-Mar-09 20:36  thanks.. actually I was looking for a syntax just like combobox1.items.clear() I am a learner Always Re: clear datagrid in vb.net 0x3c02-Mar-09 20:48 0x3c0 2-Mar-09 20:48  Unfortunately you are unlikely to get that. That is effectively a more eloquent 'send codez plz!11'. Now, the problem is that you have not said whether you want to remove the items from the DataGrid, or clear the object which the DataGrid is bound to. This will also clear it (I've not used it for a while, so you may want to check that). However, clearing the object which the DataGrid is bound to, does just that - clear it; when this has occurred, you must reload the object from another memory location or a file. Clearing the DataGrid itself doesn't touch the object. Which of the two to do you want to do? Re: clear datagrid in vb.net hrishiS2-Mar-09 20:57 hrishiS 2-Mar-09 20:57  not the object... I just want to clear the datagrid on a button click...the scope of the object is not even there in the button....Its just a button iwth a caption "clear datagrid". Doesnot concern with any object Thanks I am a learner Always Re: clear datagrid in vb.net 0x3c03-Mar-09 5:46 0x3c0 3-Mar-09 5:46  In which case, you simply need to set the DataSource to Nothing; alternatively you could simply use DataGrid.Clear(). By the term 'object' I mean the database or data source which the DataGrid is bound to. Sorry if I caused any confusion. Incidentally, you could have found your answer from Re: clear datagrid in vb.net Tej Aj3-Mar-09 7:17 Tej Aj 3-Mar-09 7:17  In order to Clear a DataGrid control having a DataSource property set to some Object, you only need to write DataGrid1.DataSource = Nothing this will clear the grid automatically. Tell me whether this solution works or not. How to use timesetevenet() in vb.net 2005? Jackeygou2-Mar-09 18:34 Jackeygou 2-Mar-09 18:34  I write some code as follow: Module mdlTimerEvent_Drive Private Declare Function timeSetEvent Lib "winmm.dll" (ByVal interval_Ms As Integer, ByVal resolution_Ms As Integer, _ ByVal lpFunction As [Delegate], ByVal dwUser As Integer, ByVal uFlags As Integer) As Integer Private Declare Function timeKillEvent Lib "winmm.dll" (ByVal uID As Long) As Long Private Delegate Sub timeCallback(ByVal uID As Integer, ByVal uMsg As Integer, ByVal dwUser As Integer, _ ByVal dw1 As Integer, ByVal dw2 As Integer) Private Const elapse_Periodically As Integer = 1 Public m_nInterruptTime As Long Private Sub TimeProc(ByVal uID As Integer, ByVal uMsg As Integer, ByVal dwUser As Integer, _ ByVal dw1 As Integer, ByVal dw2 As Integer) m_lngNewCount = m_lngNewCount + 1 End Sub Public Sub StartTimer() Dim tmrProc As timeCallback = AddressOf TimeProc m_lngNewCount = 0 m_lngTimerID = timeSetEvent(m_nInterruptTime, 1, tmrProc, vbNullString, elapse_Periodically) End Sub Public Sub StopTimer() If m_lngTimerID > 0 Then lngResult = timeKillEvent(m_lngTimerID) End If End Sub End Module I call mdlTimerEvent_Drive.StartTimer() and it run, but Vs.net show MDA exception "callbackOnCollectedDelegate" after seconds.

Initially I was doing my VB.net project using a 17 inch monitor. Now when I shifted my project to a flat LCD monitor with different resolution, my ALL CONTROLS POSITION ARE NOT LIKE BEFORE......In future I may have to shift my project to different monitor again. Moreover for deploying the project also, I don't know the resolution of clients monitor in advance.... Could anyone please give me solution for this. Thanks in advance I am a learner Always Re: monitor resolution problem Christian Graus2-Mar-09 17:38 Christian Graus 2-Mar-09 17:38  Best bet is to buy a good VB.NET book. Read it. Look up 'dock' and 'anchor' in the index for how to lay out your controls so they resize for the form. Christian Graus Driven to the arms of OSX by Vista. Re: monitor resolution problem hrishiS2-Mar-09 17:55 hrishiS 2-Mar-09 17:55  HI Christian, Thanks for your reply... I have at least 500 controls all over the project. Is there any way to do the same together or something like that.. Thanks I am a learner Always Re: monitor resolution problem Christian Graus2-Mar-09 18:34 Christian Graus 2-Mar-09 18:34  No, of course not. What magical way would there be to do that, unless you just want them all to sit on the top left of the form. Buy that book, and next time, set these things as you work on the project.

Re: monitor resolution problem praveenkumar palla2-Mar-09 17:55 praveenkumar palla 2-Mar-09 17:55  Set the Anchor property for each control according to your design Your controls will be placed according to the resolution Re: monitor resolution problem hrishiS2-Mar-09 19:35 hrishiS 2-Mar-09 19:35  thanks praveen..... So can I just select all controls on the form and set the anchor? I am a learner Always Re: monitor resolution problem Dave Kreskowiak3-Mar-09 7:10 Dave Kreskowiak 3-Mar-09 7:10  No, you can't. The controls are already anchored, by default, to the top left corner of the form. Changing the anchor for all of the controls all at once will only cause you extreme grief. Really, anchoring and layouts should have been done eariler in the apps development. It sounds like you're missing proper anchoring and proper use of flow and table layout panel controls. The bottom line is that there is no easy way around your problem. Fixing this is going to take a lot of work that you simply cannot automate or do in a day or two.

Are you saying that when this code executes, it's not putting the value of the Text property in the array?? How are you determining this??
